Model Recommendation for Object Detection

In this work, we explore an approach to generating detectors for a new detection task that is radically different from the conventional approach of learning a detector from a large corpus of annotated positive and negative data samples. Instead, we assume that we have evaluated off-line a large library of detectors against a large set of detection tasks. Given a new input task, we evaluate a subset of the models on samples from the new task and use the huge matrix of models-tasks ratings to predict the performance of all the models in the library on the new task, enabling us to select a good set of detectors for the new task.

This approach has two key advantages of great interest in practice: 1) a far smaller set of annotated samples is needed compared to the size of the training sets required for training from scratch; and 2) recommending models becomes a very fast operation compared to the notoriously expensive training procedures of modern detectors. (1) will dramatically reduce the need for manually annotating vast datasets for training detectors; (2) will enable rapid generation of new detectors.
